hello
when I shock with sodium dichlor or add mps the water turns yellow and leaves a yellow film at water level. When I run the jets it goes away. The film takes longer to go away. I test the water all the levels are in line. Whats causing this to happen ? Im using ozonator with silver ion cartridge. Im shocking once a week with dichlor (2tbls) and twice with ups (2 tbls) 500 gallon tub.
